Model 239-RTD-AN is one of the many Motor Protection Relays produced by GE Multilin to aid in the protection of motors, please note that typically the protected motors are three-phase AC motors. General Electric designed these RTD (resistance temperature detector) relays to offer full protection of the motors in some of the harshest conditions. This series (as of mid-2021) is under last-time buy status with the OEM and will soon be unavailable through General Electric.
The 239-RTD-AN offers breaker failure protection, overload warning protection, ground fault protection, and locked rotor protection. The unit includes a clear front-facing LCD display that allows users to see status, temperature, and current, along with other data. Compared to other relay protections produced by GE Multilin this particular unit is more compact and can fit most starters. Often times relays must have approvals, otherwise known as certifications to be used in locations, this specific unit is UL and CSA-approved for your convenience. Typically there are outputs associated with the 239-RTD-AN model, the specific outputs for this unit are analog and RTD outputs. Additionally, the unit has conformal coating options for these outputs.
